This is the issue seen on Apple Silicon machines:

ImportError: 
dlopen(/Users/x/venv/lib/python3.11/site-packages/arraykit/_arraykit.cpython-311-darwin.so, 0x0002): symbol not found in flat namespace '_npy_double_to_half'

This may be related to issues that others are having on M1/M2s using Python with compiled resources.

I have finally been able to configure my GitHub Action CI to build arm64 wheels on Apple Silicon runners, which is what is needed to resolve this issue.
